⚠️ PLEASE NOTE: THIS IS A VIN-PROGRAMMED REPLACEMENT MODULE. You are
purchasing a professionally remanufactured Engine Control Module that
we program to YOUR vehicle's exact VIN, engine, and transmission
combination before it ships. You do not send us anything — this unit
arrives ready to install.
After purchase, send us your 17-digit VIN through our "Contact" page.
Common Symptoms This Service Fixes:
- Check engine light with communication or internal module fault codes
- No-start / no-crank condition
- Rough idle, stalling, or misfire not tied to a mechanical issue
- Poor fuel economy from erratic engine management
- Scan tool cannot communicate with the ECM
(LML 2011-2016: DEF/emissions-related codes more common on this group.)
